To all whom 'it may concern:l J

Bo it known that we, PAUL lnssnm, a subject ai tliie Illing oliHungery'freeiding. et Homestead, and THO- Bolte Sturm, o. eubject of theEnlperornol Germany, residing at Pittobmg, in the county oi Alleghenyand Sttte of Feunovlvonia, .bave invented certain new and unefullmprovomente in .Pipe and Tube Cleaners, of

which the following in a npecication, reference being had therein to theaccompanying drawing.

This invention relates to certain new and ueeful improvements in pipeend tubecleaners, and the invention had for ite primary object the-provieion of novel meaim lor thoroughly cleaneing the inside of a pipeor To Athie end, We have dovied revolving cleaners.

which ere particularly udaptcd lor removing corrosion f and scale frompipes or tuberi,- v/lien tbe pipes or tubes sol ' have not becomeentirely clogged or ruined by tbe corrosion of the inner Walle of thepipes or tubes.

The cleanem are revolved through the medium of a liquid. or lluid forcedthrough the pipe `or tube,and artid cleaners are provided with cuttingedges similar to an ordinary auger, whereby the interiorwelle of o. pipeor vtube can be thoroughly' cleansed and the croseareo. of

the pipe orrtube returned'to ite normal slee.

cleaner will retrete ine. reverse direction to the other cleaner,'thereby insuring a perfect cleaning of the pipe or piece of tubing.

In practice, two cleanereare preferably used in re-I moving foreignmatter from the' interior of a pipe or tube, end these 'cleaners ereconnected together by providing the cleaner A with anoutwardly'extending arm 6, carrying eA socket 7 adopted to'receiveytl1e`bal-l.-end 8 of a rearwardly' extending arm 9` carried. by thecleaner B 'lhe socket 7 together with the ball arm 8 forme auniverealjoint whereby one cleaner con revolve irrespec* tive of theother cleaner.l i

The liebde ll. are retainedWithin the bores l by screw plugs 14 which are provided with stu'lingboxes 15 of a conventional form, to form a non leakable connectionbetween the cleaners and` their.

i lnorder that the cleaners may be deed in a curved l Vpipe or tube, weconstruct-some ofthe cleaners of a spherical body 24 having'cutting ribs25. The sphere ical body 24 is uned for passingiaround a curve in a pipeor tube and 'a plurality of these bodies may be connected togethersimilar to thelclezmrers and B.

The duid or liquid. under pressure striking thecuttingribe 4 causes the cleaners to rotate, the cutting iibs in thisinstance serving as blades which propel the cleaners and when backed by"a considerable present-e of liquid or iuid, 'the cleaners will beforced forwardly until the entire` .piece ofpipeor tubing has beenJcleansed.

We preferably construct the bodies o the cleaners. of 5 strongand'durable metal, and ,they may be made oi Vari'iiis sizes to fitvarious sizes of pipes or tubing.
